a pos itiveieonneetiqn heing'nmintained at all time'sf 'betw'een the .iggipper shaft and the actuator 25; .The

n meses the. of the shaft 14. 'Thei 10 plunger 33 prevents the gripper fingers from being thrown forward into premature engagement with the sheet of paper on the feed board (not shown), which cooperates with the impression cylinder.

The impression cylinder also carries the shaft 35 on which the clamping fingers 36 for the tympan37 are secured. In order to secure the fingers36 in clamping position the shaft 35 carries, outside the end wall 16 of the cylinder, an arm 38. A locking dog 39 is pivoted on the end wall 16 at 40 and has a. cam-shaped toe 4.1. which engages with the arm 38 to hold the clamping fingers 36 in the position shown in. Fig. 2. The dog39 has its end 42 adapted to engage the hub of the arm 38 as shown in Fig. 3 and any tendency for the shaft 35 to rotate in the direction to release the fingers 36 would beresisted by the coiiperation of the arm 38 With the toe 41 and the dog 39 would have its end 42 pressed more firmlyagainst the hub of the arm 38. When it is desired to release the clamping fingers 36 it is only necessary to insert a screw driver or other form of pry into the space 43 between the end 42 of the dog 39 and the hub of the arm 38 and a separation of these parts will throw the dog around to the dotted position and thus release the arm 38 and permit backward rotation of the shaft 35.

While I have illustrated what I new consider to be the preferred form of my invention it will be.understood that changes may be made in the details of construction Without departing from the spirit of the invention as defined in the claims, and therefore I do not wish to be limited to the exact details shown and described.

Having thus described my invention, what I claim and desire to, ent is 1. Thecombination of an impression cylinder, a gripper shaft, a gripper actuator,

gearing connecting said actuator with said spring means op osing the gripshaft, and ping movement of said sha t operable on a member driven by the gearing and whereby secure by Letters Pata positive connection with said actuator is maintained.

2. The combination of an impression cylinder, a gripper shaft, an axially movable gripper actuator arranged at the axis of the cylinder, gearing connecting said actuator with said shaft, and spring means acting directly on said shaft and opposing rotative movement thereof in one direction.

3. The combination of an impression cylinder, a. gripper shaft, a gripper actuator, gea connecting said actuator with said shaft, in arm on said shaft, and a springpressed member cooperating with said am andf opposin gripping movement of the sha t.

4. The combination of an impression cylinder, a gripper shaftgsg, gripper actuator, gearing connecting said actuatonwith said shaft, an arm on said shaft, and a springpressed member carried by the end wall of said cylinder and engaging said arm and opposin gripping movement of said shaft.

5. The combination of an impression cylinder, a gripper shaft an axially movable gripper actuator, a me carried by said actuator, a bevel gear on said shaft, a stud car.- ried by said cylinder, and gears rotatable on saidv stud and meshing withs'aid rack and said bevel gear and forming a driving connection therebetween.

6. The combination of an impression cylinder,

a gripper shaft, a gripper actuator,

gearing connectin said actuatorfwith said shaft, and means or preventing'l'ostmotion' in the mechanism comprising yielding means opposing the gripping movement of said shaft and operable on a member driven by, said i'nder, a gripper shaft, a gripper actuator, gearing connecting said actuatorwith said shaft, wielding 'means opposing the kmove ment. of said actuator .in one direction and means for preventing lost motion in, the mechanism.
